You don't understand how spending your time promoting and advertising something you claim to be useless is silly, irrational or inconsistent?
You are proud to be getting paid for something you seem to know is worthless, not contributory and you admit that you should not be getting paid as much?
I don't know. I just think so. And as I mentioned earlier I can be wrong. The fact I wear signature doesn't harm anyone. There is a slight chance it doesn't benefit anyone either. That's why I don't see any inconsistency in my behavior. A smoker analogy is not the best in this case (btw many smokers DO say smoking is bad and no one should do that). I'd rather say I'm a Formula 1 driver who takes money for wearing Toyota underwear - it doesn't harm anyone, it doesn't benefit anyone (probably) but if Toyota thinks it'll help them in some way and they're ready to pay for that - why should I refuse?
You're right, you don't have to believe a signature is a good advertisement to wear it, but it proves how easily you will sell-out and promote something you don't agree with, are actively campaigning against and believe to be worthless.
As I said I promote only those projects I like. In the case signature make any difference.
